| 1. An apparatus to generate a high voltage, comprising:
a switching part to control a voltage induced in a secondary coil of a power transforming part, by interrupting a current
of a primary coil of the power transforming part; and
a digital controlling part to control an interruption operation of the switching part according to control data, having:
a frequency modulating part to generate a synchronize signal corresponding to a moment when the switching part requires a
minimized resonance voltage to perform the interruption operation; and
a voltage modulating part to perform the interruption operation corresponding to the synchronize signal and to modulate a
cycle of the interruption operation of the switching part, according to comparisons between a reference voltage determined
from the control data and a feedback signal corresponding to a second output voltage of the power transforming part.
